To all whom it may concern:

Be it known that I, HENRY A. Wren Wool), a citizen of the United States, residmg at New York in the county of New York and State of New York, have invented a new and useful Bundling Delivery for Folders, of which the following is a specification.

This invention relates to an improved delivery mechanism for printing machines especially adapted to that klnd of delivery usuall used in connection with the folders of we printing presses, but it is capable of general use.

The principal objects of the invention are to provide for automatically and accurately bundling sheets, papers or books, thus doing away with the hand labor now required ordinarily for this purpose; to provide a construction in which this bundling can be done at the high speed necessary in delivering the product from certain modern high speed web presses; and to provide means for delivering the sheets wlthin easy reach of the operator or to a table or elevator. The invention also involves improvements in the features of construction as will appear hereinafter.

Reference is to be had to the accompanying drawings in which- 4 Figure 1 is a front'elevation of a machine constructed in accordance with this invention;

Fig. 2 is a plan of the same; and

Fig. 3 is an enlarged detail view in side elevation of a part of the mechanism.

Heretofore papers have been fanned out on running belts and every fiftieth or one-hundredth sheet thrown out of position for counting purposes forwardly by a movable finger at the rear. As the belts carry the sheets from the folder a delivery boy has been employed to reach down and take up in his arms the full number counted. He then had to jog them into a bundle on a table before he stacked them up and carried them away. At the high rate of speed at which modern web presses of a certain type are run, there is not sufioient time for this work, and it is desirable, of course, to perform it automatically in order to reduce the expense for labor.

This invention is designed for that purpose, and for the,purpose of accurately and endless tapes or belts 13. it is to be understood, however, that the mechanism can be used in connection with any other machine havin a continuous delivery. Stationary curve guides 17 are shown for guiding the sheets as they are lowered by the fans. The fans 12 are shown as on a driving shaft 14 which by means of a vertical shaft 15 and gearing drives a cam shaft 16. It is from this shaft that the belts 13 are driven directly. On this shaft is a stop cam which I operates an arm of a lever 21. The other end of this lever is adjustably connected with a link 22 pivoted to an arm 23. This arm swings a shaft 24 having arms 25 on each which is a stop 26. These stops oscillate about the shaft 24 and are moved by the cam periodically. Connected with the ghait 24 is a spring 27 for holding the stop A sprocket 30 on the shaft 16 is provided with a chain which operates a shaft 31. This in turn operates an endless carrier 32 provided with a plurality of fingers 33 pivotally mounted thereon. These are provided with rigid arms 34 at the ends of which are cam rollers 35. Su ported on a shaft 36 are cam plates 3 adjustably mounted by means of slots and bolts 38. These are in position to engage the rollers at certain times and operate the fingers as will be described hereinafter. The car riers are connected to travel faster than the belts 13.

Mounted on the shaft 16 is a hold-back cam 40. Through levers 41, operated thereby, and links 42 this cam accomplishes the oscillation of arms 43 mounted to swin on the shaft 14. Connected with this s aft are a plurality of arms 44 at the ends of which are hold-backs 45. These are adapted to be automatically dropped into position to obstruct the forward movement of the first few sheets of each bundle.

The operation-is as follows :*The folded product from the press is delivered in the usual manner from the folding and cutting arrangement through the rollers 11 and fans 12 to the belts 13, preferably one sheet or book at a time. As they are delivered on the'belts they strike against the stops 26 and are given a continuous forward motion through most of the period of a complete revolution of the shaft 16. en a predetermined number of sheets have been delivered to the belts the end of the lever 21 suddenly drops from the high part of the cam to the low part. This releases the stops 26 so that they assume-their ori 'nal position. That is, they suddenly go ack from the dotted line to the full line position in Fig. 1. Now when the next sheet is faster than the belts 13,

. fingers reach the position 33* for delivered on the belts it is obvious that there.

will be a "space between its rear edge and .the rear edge of the preceding sheet equal to the distance whichthe stops fell back. This marks the count. The parts are so timed that at this moment a series of fingers 33 come into position to engage the rear edge of the preceding sheet. Being driven and being controlled by the cam 37, they have a comparatively sudden upward and forward motion. Thus they gradually close up the bundle of sheets until at the dotted line position of these 'fingers (33) the stack of sheets is completed. Then the bundle is carried forward at the same speed by the fingers to be taken off at will by the operator or delivered to a table or elevator. When the they run off the ends of the cam plates 37 andremain ino erative until again picked up by the opposite ends of these cam plates. At the moment the fingers 33 start to pick up the rear sheet of a bundle the hold-backs 45 are automatically dropped into position by the action of the cam40. Thisobstructs the forward movement of the first few papers of the succeeding bundle until enough of their surface comes into contact .with the belts 13 to insure their not being carried forward by the faster moving preceding bundle.

In this way it will be seen that the sheets are automatically bunched in bundles of a definite number, as for example, fifty or onehundred sheets each, and that for practical purposes, the sheets of each bundle are automatically counted out. The mechanism is.

of such a character that it will operate at the highest rate of speed at which the modernrotary web presses are operated, and

its work is accurate and entirely automatic. Although I have illustrated and described a preferred embodiment of the invention,

only and shown it as applied to only one type of delivery mechanism, I am aware of the fact that many modifications can be delivering,

made in the arrangement of parts and details of construction when applied to this type ofdelivery, and that it can be applied to other types of delivery either with or without corresponding changes. Therefore, I do notwish to be limited in these respects, but what I do claim is .1.. The combination with an endless conveyer and means for delivering sheets or the like thereon, of a stop for the rear ends of said sheets, means for continuously advancing said stop in the direction in which the conveyer operates and forthen retracting it, and means for moving the sheets forward on the conveyer to form a bundle while the stop is retracted.

2. The combination with a conveyer and means for delivering sheets or the like thereon, of a stop movable adjacent to said conveyer for engaging the rear edges of the sheets, means for moving said stop forward with the conveyer until a predetermined number of sheets have been deposited on the conveyer and for thereafter suddenly retracting said stop, and means to thereafter move the predetermined number of sheets forward relatively to the conveyer to form a bundle.

3.
